Selon Bob Friesenhahn <email@example.com>:
Recently, Frank Warmerdam made a few changes in libjpeg CVS to built it for 12 bits/sample mode, in a way it can coexist with the standard 8 bits/sample. This work has been integrated in GDAL SVN head and used by its internal libtiff for example. Look at http://trac.osgeo.org/gdal/wiki/TIFF12BitJPEG for more details.
Hello, what is the meaning of the define JPEG_LIB_MK1?
There is a development version of libjpeg (based on 6b) in the same CVS repository as libjpeg which supports 8 and 12 bit bits/sample in the same build. Unfortunately, this libjpeg was never quite completed and since there is now a JPEG 7 release and a JPEG 8 under development, I am afraid that the project has become orphaned.
